GCE FIT+ one Tool-Free Machine Cutting Torch

A tool-free injector torch for machine oxy-fuel cutting

The GCE FIT+ one is a machine cutting torch for oxy-fuel cutting machines and gantry cutters. GCE built the line around a tool-free nozzle system: cutting nozzles are fixed by hand with a bayonet system, without a wrench, which cuts nozzle-change time and makes the torch easier for machine operators. The torch is an injector type with an axial injector and, in the acetylene versions, a Resonator Mixing System (RMS); a COOLEX cooling system is built in. It is made in accordance with ISO 5172.

GCE states that FIT+ one cuts straight and shape cuts to ISO 9013 in steel from 3 to 300 mm, pierces holes up to 150 mm, and works with different fuel gases. One type of heating nozzle covers all fuel gases, and GCE says this extends the life of the heating nozzle. The torch is prepared for all cutting machines.

Nozzles and cutting parameters

GCE publishes cutting parameters for FIT+ one, FIT+ two and FIT+ three in a single sheet. For acetylene, the ASF high-speed nozzles run from 0769923 (3-5 mm plate) through 0769924 (6-10 mm), 0769925 (10-25 mm), 0769926 (25-40 mm), 0769927 (40-60 mm), 0769928 (60-100 mm), 0769929 (100-150 mm), 0769930 (150-230 mm) to 0769931 (230-300 mm). The ARC rapid-cutting nozzles F25510003 (3-40 mm) and F25510004 (3-70 mm) are listed for higher speed on thinner plate. Heating nozzles are 0769932 (3-150 mm) and 0769934 (150-300 mm).

For propane the PSF nozzles run from 0769913 (3-6 mm) to 0769922 (250-300 mm), and PRC rapid-cutting nozzles are F25510001 (5-40 mm) and F25510002 (5-70 mm). As an example of the published speeds, 10 mm plate cut with acetylene and the 0769924 nozzle is listed at 710 mm/min, and 100 mm plate with 0769929 at 270 mm/min. The sheet also gives, for every thickness, the oxygen and fuel pressures, preheating and piercing times, torch height and kerf width, and the same tables apply to the FIT+ two and FIT+ three torches.

Selecting and setting up

Select the torch length and fuel gas first, then the nozzle for the plate thickness range. Fit a flashback arrestor for machine cutting torches at each gas inlet, and keep cutting-oxygen channels clean with the correct cleaning needles rather than drills. Check the cutting parameter sheet before programming speeds, since the values depend on gas, nozzle and plate condition.

How the GCE FIT+ one works

The FIT+ one is an injector-type machine cutting torch. Oxygen flows through an axial injector and draws the fuel gas into the mixing chamber, so the torch needs no high pressure fuel supply. The mixed gas burns at the nozzle as a ring of preheating flames. When the steel is hot enough, a separate stream of pure oxygen is released through the centre of the nozzle and burns a narrow cut. A built-in COOLEX cooling system protects the torch head, and the acetylene versions use a Resonator Mixing System to keep the flame stable.

Where the FIT+ one is used

• Oxy-fuel gantry cutting machines
• Plate and profile cutting in steel fabrication
• Shape cutting to ISO 9013 quality
• Shipyards and heavy plate shops
• Machines that run acetylene, propane or natural gas

Selection checklist for the FIT+ one

• Cutting thickness from 3 to 300 mm
• Piercing capacity up to 150 mm
• Fuel gas: acetylene, propane, natural gas or mixed gas
• Nozzle family: ASF, ARC, PSF or PRC
• Connections: G3/8, G3/8 left-hand or G1/4
• Torch length and diameter to fit the machine holder
• Article number of the torch
• Heating nozzle for the plate thickness

Installation, commissioning and maintenance notes

Fit the torch into the machine holder, connect the oxygen and fuel hoses to the right threads, and check each joint for leaks. Fit the nozzle by hand with the bayonet system, with no tool needed. Light the torch as the maker advises and set the pressures from the cutting chart for the plate thickness. Clean the nozzle bore regularly, and replace damaged nozzles at once, because a bad nozzle spoils the cut edge.
